Speaking from my experience as a person with the disease and someone who has worked with others who have it, PD affects so much: rhythm and cadence, tempo and affect volume (vocal and movement), and control. We consider these listed in musicality but not as often in the context of our movement.

How does loss of rhythm and cadence impact control over the body as a PD Athlete?
It removes" flow" and strips you of any pattern, sequence, or tone to ascribe your movement. It causes you to feel "herkie-jerky," akin to a child pressing keys on a piano for the first time. There may be an occasional semblance of pattern for movement, but smoothness or that feeling of "just right" will escape you.

With PD, we seem to be absent of flow but not removed. We witness this in athletics and hear it in concerts of artists the same, those who are in a "slump" or going through "it." They may go without a catch, hit, or goal or have a concert that doesn't resonate with the audience. They have lost the flow.
But, as with professional athletes, we have the opportunity and obligation to rise to such an occasion and regain every ounce we can. But how?

Self-exploration, play, joy, fun, and adaptation.
Indeed, we are enjoying a sled ride of descending adventure. But as we glide on down, may we glance to each side and take in the beauty around us.

Each journey is different, unexpected, and challenging. But if we choose to experience it as such, it's much like a crescendo amid a beautiful melody: powerful and flexible, fulfilling and cleansing.

Now, I challenge you to hear the music of your life and your soul more than you listen to what ails you. Find your flow and live.
